I love love LOVE this product - by far the most relaxing bath I've had. It is my go to whenever I need a little help relaxing before bed.
Love this product especially when I am sore from the gym!
Fantastic to now be able to buy even more of my favourite soaks in bigger refill packs. Thank you!
Love being able now to buy more of my favourite bath soaks in refill packs. The same luxuriously beautiful soak, just more of it in one.
I held off buying these for ages, thinking they're just too expensive, I can't spoil myself to such an extent. But then I gave in and am so so glad I did! Truly the most wonderful, soothing baths I've ever had. Have now purchased and used many various blends and will keep on using them. Absolutely worth it!
